No wonder Griffin has been portrayed as Superman in a nation's capital that waited more than a generation for a franchise player at the league's most important position.
However, in Sunday's wild-card game against visiting Seattle, Griffin reinjured his knee twice, and his ailment helped the hard-charging Seahawks rally from an early two-touchdown deficit and beat the Redskins 24-14.
Griffin was re-injured in the first quarter, but he remained in the game until he was hurt again with 6:19 remaining.
The extent of Griffin's injury won't be clear until he undergoes an MRI, but after lying on the field a few minutes, he walked off without assistance. He later walked into and out of his press conference without a noticeable limp.
"Coming off the field I thought it was just the same thing, but we'll see what it is," Griffin said.
Griffin's exit came in the wake of a USA Today report that famed surgeon James Andrews, who is on retainer with the Redskins, hadn't cleared Griffin to return after the quarterback was initially injured in Week 14 against the Baltimore Ravens. Griffin was more seriously injured later in that game, and he missed the following contest at Cleveland. Andrews was on hand Sunday as Griffin hurt the knee when he planted on a first-quarter throw to receiver Pierre Garcon.
"Doctors always worry anytime somebody has an injury, rightfully so," said Redskins coach Mike Shanahan, adding that Andrews cleared Griffin to continue after Sunday's early knee injury. "They clear a player if they think he's able to play, and we obviously take their recommendation very seriously. ...
"(During the Baltimore game, Andrews) said, 'Robert started showing us he could run.' He felt Robert was OK to go back in. I promise you, if we thought it had something to do with Robert's career and his injury, we would've (taken) him out."
Shanahan's statement was in sharp contrast to Andrews' comments to USA Today, as the orthopedist said he didn't examine the quarterback before Griffin returned to face the Ravens.
